Don't think 6000 is gonna get it buddy. Minimum I would go would be 8000, and that's minimum. You have to think that if the truck is going uphill then you have even more of a load stressing the winch and it is going to need even more power to pull the truck.

Yep..8,000 minimum.i had an 8k on my old 4runner, pulled it like a champ..if you look you can find brand new ones for around $500..my milemarker was buy one get one free..when i bought my 8k, they sent me a 2,000# for free so i have a brand new 2000# winch sitting in a box still
